Answer:

y=|x-7|-9.

Step-by-step explanation:

The given function is  y=|x|.

When this function is translated to the right 7 units and down 9 units, then the equation becomes

y=|x-7|-9.

Always remember that; y=|x-c|-k is a transformation that translates the graph of y=|x| c units to the right and k units down.

The correct choice is the first option.

2/3a = -24<br><br> Please solve the equation and show how you got the answer! (:
devlian [24]
You have to isolate the (a) so you multiply the 2/3 by 3/2 and you have to do that to the right side. So -24 times 3/2 equals to -36. Therefore, a=-36.

4 students is what percentage of 20 students?2 doctors is _____% of 25 doctors.
Ray Of Light [21]

In both cases, we can use a rule of three.

<h2>First part</h2>\begin{gathered} 20\text{ students}\rightarrow100\text{\%} \\ 4\text{ students}\rightarrow x \\ x=\frac{4\text{ students}\cdot100\text{\%}}{20\text{ students}} \\ x=\frac{4\cdot100\text{\%}}{20} \\ x=\frac{400\text{\%}}{20} \\ x=20\text{\%} \end{gathered}

Therefore, 4 students correspond to 20% of 20 students in total.

<h2>Second part</h2>\begin{gathered} 25\text{ doctors}\rightarrow100\text{\%} \\ 2\text{ doctors}\rightarrow x \\ x=\frac{2\text{ doctors}\cdot100\text{\%}}{25\text{ doctors}} \\ x=\frac{2\cdot100\text{\%}}{25} \\ x=\frac{200\text{\%}}{25} \\ x=8\text{\%} \end{gathered}

Therefore, 2 doctors correspond to 8% of 25 doctors in total.
